As the focus on per- and polyfluoroalkyl substances (PFAS) intensifies, multiple states and some U.S. federal agencies are implementing or considering implementation of restrictions or bans on the use of these products in food contact articles. The problem for food companies and suppliers to the industry is that these restrictions and bans are not consistent and, therefore, determining compliance presents numerous challenges.
This article focuses on the restrictions and bans in the U.S. that impact the use of PFAS in food packaging, and includes a discussion of the challenges manufacturers face due to inconsistent science and policy decisions related to the use of these chemicals in food packaging. It is important to note that food-contact materials are only one source of PFAS. They have also long been used in fire extinguishing foam; in stain and water-repellent materials used on clothing, upholstery, and other fabrics and textiles; and in personal care products, such as certain shampoos, dental floss, and cosmetics. Due to this widespread use, PFAS have been found in soil and water at or near waste sites and manufacturing or chemical production facilities that use or produce PFAS.
